5种主要出口竹笋产品碳足迹评估与减排路径分析OA北大核心CSTPCD

[Objective]This study aims to assess the carbon footprint of bamboo shoot products and explore their emission reduction potential,so as to promote low-carbon and high-quality development of the industry.[Method]Based on the field survey data from 2022 to 2023 in Lin'an District of Hangzhou City and Anji County of Huzhou City,Zhejiang Province,this study assessed the carbon footprint of five different types of bamboo shoot export products(seasoned bamboo shoots,hand-peeled bamboo shoots,dried bamboo shoots,boiled bamboo shoots,and fresh bamboo shoots)during the planting,production and distribution stages,identified carbon emission hotspots,designed emission reduction pathways,and calculated emission reduction based on scenario assumptions.The implied carbon emission and carbon emission intensity of bamboo shoot export products in China were estimated according to the export situation of bamboo shoot products in China from 2015 to 2023.[Result](1)The carbon footprint of the five bamboo shoot products from large to small was as follows:seasoned bamboo shoot(1.387 4 kg·kg-1),hand-peeled bamboo shoot(1.010 7 kg·kg-1),dried bamboo shoot(0.927 4 kg·kg-1),boiled bamboo shoot(0.324 9 kg·kg-1),and fresh bamboo shoot(0.174 8 kg·kg-1).The carbon footprint composition analysis showed that the carbon emission hotspots of the five bamboo shoot products were mainly agricultural inputs,fresh shoot transportation,fresh shoot processing and additive inputs.(2)From 2015 to 2023,the average annual implied carbon emission of bamboo shoot exports in China was 1.84 8 2×105 t,with an average carbon emission intensity of 0.966 9 tons per 10 000 yuan.(3)The emission reduction scenario design based on carbon emission hotspots showed that the average decrease in carbon footprint of the five bamboo shoot products in 2023 was 20.15％.[Conclusion]There are significant differences in the carbon footprint of different types of bamboo shoot products.The implied carbon emissions of bamboo shoot products exported from 2015 to 2023 show a fluctuating downward trend.The comprehensive implied carbon emission intensity shows a fluctuating upward trend.The carbon emission hotspots of bamboo shoot products vary,and there is potential for further reduction in carbon footprint through emission reduction measures.[Ch,2 fig.7 tab.36 ref.]
